PATENT "OFFICE.

To all whom it may concern:

Be it known tha I, OLIN J. Gi'mLooK, of

Palmyra, in the co nty of Wayne and State v of New York, have invented anew anduseful Improvement in Rod-Packin which improvement isfully setforth in t e following s eciiication and shown in the accompanyingrawings.

This inventlon relates to certain new and, useful improvements 1n ringpackmgfor p1s-- ton and pump rods, and it has for its objects amongothers to provide a sim le.and;efii-' the stufiin box at the end of thecylinder short and s allow so as not to" roject too far 1 from the endof the cylinder, t e'packingbe ing such that a few rings are sufiicientto per- 'fectly'pack the rod and keep the joint around it tight andprevent the escape of the water.

The present improvement is applicable to rings Whether the wear comes onthe outer or the inner periphery or. circumference. The metal ring is ofsubstantially V-sha e and its inclined sides are embedded in the bodyportion of the packing ring, which made of suitable material, as layersof fiber as cotton duck or other analogous substance alternated withlayers of india rubber, both faces of which are preferably faced withrub ber. In all instances the metal member or ring has its ends slightlyapart to' rovide for eing pra'ctica across, and in the case of a. ring apted for rods the body portion is out across diago nally. In the formdesigned for piston heads or plungers the body is notcut as there is nooccasion therefor, these rings being used to The metal strand is cutacross so as to allow it to ex and or be ex anded to press the innersuriiice of the cy inder.

Other objects and advantages of the inven-' tion will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

to be received the ring 4 preferably of as seen best in Fig. 1. ring hasits ends separated as seen at 5 so as to allow for expansion in use. Inthis form the body portion 1 is cut diagonally across, as seen at 6, sothat the said body may be expandedby the expansion of the lead ring. I Apacking ri'ngthus constructed, with the lead member on the inside isdesigned for rods .and may bemade of any required diameter, in sizesfrom a few inches to several feet. Any number of rings may be employed,-but the nature of my im roved packing is such that aminimum num er ofrun s is sufiici'ent to insure a. tight joint. The ead member a receivesthe abrasion or wear, as it does also ts various forms, is

in the form now to be described which is designed for cylinders, thelead member being on the outside so as to receive the wear or abrasionas will be clearly understood from reference to Figs. 4, 5 an 7 to whichattenview, wlth a'portionbroken away and arts Fig. 3 isanedgeviewof-Fig. 2.

The I be y portion is formedabout its outer periphcry or circumference with a substantially V-shaped depression, groove or recess 9 to receive the \I-shapedmember 10preferably of lead. The ends of this lead member or ring 10 areseparated or spaced apart, as shown at 11, to allowfor expansion. Inthis form the fibrous and rubber body8 is notprovided with a diagonal orother out as there is no occasion for the same, this formof packin ringbeing designed for piston heads or plungers and used for sucking orpumping water. The lead member 1s cut across or separated so as toexpand or be expanded to press the inner surface of the cylinder.

in Fig. 1, 12 designates the piston rod while in Fig. 7 13 designatesthe cylinder or pump barrel and 1 1 the plunger rod, it being understoodthat these parts are of ordinary construction.

In Fig. 6 I have large d ameter having embodied therein rings of thecharacter shown in Figs. 1, 2 and 3. i In this form the end rings 15 and16 are thin rings of alternated layers of fibrous material and indierubber, next adjacent which are the rings 17 and 18 respectively whichare similar to those shown in Fig.1, 19 being the lead members or ringson the inner surfaces thereof, and between these rings are the rings 20,the body portion of which is of rubber having embedded therein theannular disposed metal rods or the like 21. This forms a most efficientform of packing ring for heavy hydraulic work, it being understood 1that any number of the alternately disposed shown a packing ring offiber, as cotton duck l rings may be em loyed, according to the desiredlength of t e completed packing rings. It is to be understood that thedifferent forms of rings hereinbefore described are for 1 either hot orcold water; it is also evident that various modifications in the detailsmay be resorted to without departing from the spirit of the invention orsacrificing any of its advantages.

-What is ilaimed as new is 1. A ac in rin com risin a bod 0rtion of alternat e lay ers of rubb r and iibibus material having a surroundingsubstantially V-shaped recess and facings of rubber upon op oslte sides,and a ring of lead substantia ly \I-shaped in cross section looselyseated in. said recess and having its ends spaced apart to allow forexpansion.

2. A packing ring composed of end rings, rings adjacent the same andcomposed of a body portion of fiber and rubber and a lead ring looselyseated therein with its acting face disposed to receive the wear andabrasion in use, and a ring of rubber interposed between the ringshaving the lead rings.

3. A (packing ring composed of end rings, rings a jacent the same andeach having a lead ring upon its acting face with the ends separated andloosely seated in the body portions of said rings, and rin s of fiberand rubber with reinforces embedded therein and interposed between therings having the lead rings.

In witness whereof, I have hereunto set my hand this 30 day of April,1908, in the presence of two subscribing witnesses.
